The bemused presenter said: “I can see the point that you might question 9/11 but if you also think that Buckingham Palace is inhabited by lizards, it kind of undermines you.”

But Icke defended his views saying: “It’s not that simple. The whole big back story before you get to what I’m saying, if you deliver it in one line - ‘the world is run by reptiles’ - you meet on one level.

“’Oh that’s crazy’, immediate reaction.

“But when you see the back story and the evidence to support this, ancient and modern, you see that one throwaway line in a completely different context.”O.....K.

1) The Portland Communications saga

In June pro-Corbyn website The Canary outlined a series of loose connections and statements made by Portland Communications employees and advisors in a much derided article claiming to be some sort of explosive exclusive.

The Canary’s strange, yet popular, theory goes like this: Portland was set up by Tony Blair’s former deputy communications chief Tim Allan. On its books are a number of Labour types, many of whom dislike Corbyn and also have links to the Fabian Society. The PR firm also has “countless links to the media” and the BBC recently interviewed a Portland consultant. Err, that’s it.

That Portland Communications stuff is full lizard. Good to know that Len McCluskey is an avid reader of the Canary.
